Hackers have sent a new email to Sony Pictures Entertainment, praising the studio as "very wise" to cancel the release of "The Interview" and saying Sony's data is safe "as long as you make no more trouble."
The email was confirmed Friday by a person close to the studio who requested anonymity because the person wasn't authorized to speak publicly about the matter.
The message warned to "never" release the film "in any form," including on DVD. The email was sent to several employees of the Culver City, California company.
The Obama administration on Friday formally accused the North Korean government of being responsible for the devastating hacking attack.
